The map in Figure 9-37 reflects a view of <I>only</I> those customers who were identified in the decision tree as having a higher than average number of sales, the consumers of HOME ESSENTIAL products. This market segment, identified by the previous decision tree, can be further visually analyzed using this data mining tool. Simply by selecting the state of California, additional insight can be gained at the county level, as shown in Figure 9-38.</FONT><FONT FACE='Times New Roman, Times, Serif' SIZE=3 COLOR=#FFFF00><!-- break --></FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{B10}'/></FORM></P></TD></TR></TABLE><P><FONT SIZE=0 COLOR=WHITE></CENTER><A NAME="bottom"> </A><!-- netLibrary.com Copyright Notice --> </BODY></HTML>⌨️ 快捷键说明
